If there's one thing we know about children, it's how quickly and easily they can become completely enchanted by something, and little Prince George is no different.
During a visit to the Acorn Children's Hospice on Tuesday, Prince William told a group of children about his five-year-old son's latest obsession, because they just so happened to be playing with it.
The children in the room were making and painting dinosaurs, so Prince William told them: "George is obsessed with dinosaurs. We've been learning all about them."
Cute! We can absolutely imagine young George having a grand old natter about the prehistoric creatures to anyone who'll listen to him!
It's clear William is every bit the doting father we'd expect.
Speaking previously about his second eldest child, Princess Charlotte, Prince William revealed she is "obsessed" with fashion, "mad about pink" and "loves dancing."
The Duke of Cambridge has shared some quirky anecdotes about his family of late, and we're hoping to hear many more!
